    Not fixed in 2018.3.9 despite the release notes stating:
    Particles: Fixed "Internal: JobTempAlloc has allocations that are more than 4 frames old" error message
    It then references this Issue ID in brackets.

    I reproduced it using the exact 4 steps listed above.

    Also note that it's a warning, not an error, and lists another warning beneath it stating:
    To Debug, enable the define: TLA_DEBUG_STACK_LEAK in ThreadsafeLinearAllocator.cpp. This will output the callstacks of the leaked allocations
